1 Claim.

The object of the invention is to provide a jet closet in which the jet is so related to the siphon that siphonic action in the latter is created by direct pressure in the up-leg of the 5 siphon rather than by induction as in the conventional practice; to provide a jet closet in which the jet is so arranged that there will be no likelihood of contamination of the flush tank water by the forcing of soil water through the jet and into the tank in the operation of removing stoppages in the closet; and to provide a closet of the kind indicated in which the jet is so incorporated that the closet may be of comparatively simple form and susceptible of cheap manufacture.

With this object in view, the invention consists in a construction and combination of parts of which a preferred embodiment is illustrated in the accompanying drawing, in which:

Figure 1 is a central vertical sectional view of a closet constructed in accordance with the invention.

Figure 2 is a sectional view on the plane indicated by the line 2-2 of Figure l.

' In carrying out the invention, the jet stream is introduced into the closet bowl in the same direction that it is desired to start the movement of the Water in establishing siphonic action. Its point of application is in the well of the trap 10 directly ahead of the entrance to the up-leg 11 of the siphon and it is derived from a duct 12 formed in the thickened portion 14 of the wall of the bowl with its intake in communication with the rim 15, the bottom wall of the latter being provided with the usual perforations 16 to provide the wash-down jets for the side walls of the closet.

In the illustrated embodiment of the invention the flush tank 17 is mounted directly upon the Jcloset at the back with its discharge 18 in communication with the rim by reason of the chamber 19 intervening between the two. The tank may be supported above the closet according to the conventional practice.

Whenthe flush valve is opened by actuation of the handle 20, the water is discharged through the outlet 18 into the chamber 19 from which it passes to the rim 15, some passing through the perforations 16 to cleanse the side walls and the 5g remainder entering the duct 12 at the front of the closet and issuing from the lower end of the duct or discharge mouth 21, when it is directly in front of the entrance to the up-leg 11 of the siphon and has a tendency to push the water in the well and in the up-leg into the down-leg 22 of the siphon, thus creating siphonic action. It also serves to dislodge any solid matter in the bowl and force it into the up-leg of the siphon.

The trap well 10 is formed as the zone of a sphere and the under wall of the up-leg of the siphon as well as the under wall of the duct 12 constitute generally tangential extensions of the trap well. But the siphon up-leg and duct being oppositely disposed, they are, therefore, arranged on divergent lines. The discharge mouth 21 of the duct is cross-sectionally of less area than the cross-sectional area of the duct and the lower side of the discharge mouth is formed by the bottom wall of the bowl. The discharge mouth thus being cross-sectionally reduced, velocity is given to the jet against the bottom wall of the bowl. The discharge mouth of the duct and the inlet to the up-leg of the siphon are substantially in the horizontal plane of the center of the arc of the well trap and the jet, issuing from the discharge mouth, is delivered to the well against the curved wall of the latter, being gradually directed into the up-leg of the siphon, so that there is a tendency to create quick movement of the water in the up-leg of the siphon and to drive any solid matter into the up-leg and thence into the down-leg.

By positioning the jet duct 12 at the front of the bowl and feeding it from the rim 15, a relatively high velocity is acquired by the jet water prior to its entrance to the well of the trap.

In the event of stoppages in the closet, such as are removed with the conventional rubber force pump, there is no tendency to transfer contaminated water to the flush tank, since the only way that it could occur would be to force the water back up through the duct 12 and in the rim and thence into the chamber 19 and past the flush valve into the tank. But before this could happen, any Water forced up through the duct, would return to the bowl through the perforations 16 in the rim. Where the jet is disposed at the bottom of the Well and derives its water from the chamber below the well, the operation of removing a stoppage will result in forcing soil water through the jet and into such chamber from which it may be transferred by the pressure to the tank past the flush valve.

The invention having been described, what is claimed as new and useful is:

A closet having a Well of substantially the formation of the zone of a sphere, a siphon having its up-leg in communication with the well at substantially the center of the arc of curvature of the latter, a hollow rim in communication with a source of water supply, the wall of the closet up-leg of the siphon being substantially tangential continuations of the well wall, the discharge mouth of the duct being of less crosssectional area than the cross-sectional area of thefduct, the under side of the discharge mouth being formed by the wall of the well.
